Air Products' shielding gases are commonly used in several welding processes, mainly MIG/MAG and TIG welding. The selection of a suitable welding gas is essential for the welding process. The welding gas not only protects the weld metal from the surrounding air, it can also contribute to higher productivity and to better mechanical properties of the weld.
Air Products offers a full range of standard shielding gas mixtures for MIG/MAG welding for all common material types.
MIG (metal inert gas) and MAG (metal active gas) welding are widely used wherever medium and high fusion rates are required. Both techniques use a DC arc burning freely between the workpiece and a wire electrode, which functions simultaneously as a power carrier and a source of filler metal. . For MIG welding, the gas is inert: argon or an argon-helium mix. MAG welding uses a mixture of argon with an active gas such as oxygen, CO2 or both.
Our standard gases are available in traditional cylinder sizes at 200 bar and 300 bar cylinder pressure.
